OIL-SAVER.

the oil saver shown and described in Letters Patent granted to me April1, 1902, No. 696,747, by providing a vertically divided or two-partconstruction in the form of a slotted casing closure for entering thecable, with a device removably fitting and secured in the slot andcorresponding thereto in size and shape, thus avoiding any break in thecontour of the closure due to the slot.

A further purpose is to arrange the closure with a portion of its bodybeneath or below the cap portion, thereby lowering the device withrelation to the casing head of collision with the temper screw whichfrequently works in close proximity thereto on its down strokes.

In the accompanying drawings, Figure 1 is a vertical section of a casinghead with the oil saver in position thereon, the same being taken online 11 of Fig. 2, and Fig. 2 is a sectional plan on line 22 of Fig. 1.

-Fig. 3 illustrates the improvement in side elevation. 'Fig. 1 is a topplan of the same with the packing compressor removed, also with theslot-closing member shown out of the slot. Fi 5 is a de'tall of thepackingcompressing screw.

Referring to the drawings, 2 is the casing,

and 3 the casing head having the usual discharge pipe connections 4. Thecap 5,

the open top of head by screws t ,is preferably formed integral with theupright body-portion 7, in the embodiment shown being locatedsubstantially midway between the upper and lower ends Passage 8extending vertically through body 7 is enlarged above its lower end toreceive packing 9 which surrounds the I cable 10, preventing oilfromleaking as the cable reciprocates. Passage or cavity 8 is threadedinternally to receive the packingg screw 11, the latter bcing-heceishown split longitudinally, as in my former patent, so as to be readilyapplied and re- 1 moved. At one side of passage 8, body 7 tSpecification of Letters Patent.

and cap 5 are formed with a vertical cableentrance slot 12 in which istitted the closing member 13, having a part 11 corresponding to theslotted portion of body 7 and part 15 corresponding to the slottedportion of the cap, so that when said device is in place there is nobreak in the contour of either the body or cap due to the slot 12.Closing device 13 may be formed above and below cap portion 15 with lugs16 which fit betweencorresponding lugs 17 on body 7 with screws 18extending through apertures in the lugs and holding member 13 in place.The inner face of the upright portion 14 of the slot-closing device 13is threadedlto former devices, and hence is not so liable to be struckby the temper screw which on the down stroke of the cable frequentlyworks quite close to the oil saver.

T he improvement is of simpleconstruction, and minimizes the danger ofleakage.

I claim:

1. A casing closure formed with a vertical passage through which thecable 0perates, packing and packing compressing means in the passage,the closure at one side of the passage formed with a verticalcable-entrance slot, and a member removabl v fitting within and closingthe slot, said member shaped in conformity with the closure and when inplace preventing any break in the continuity of the closure due to theslot.

2. A casing closure consisting of a body having a vertical cable passageof sufficient size .to receive parking around the cable, a cap membercarried by the body for closing a casing-head ope ing, the body and capat one side of the passage formed with a vertical cable-entrance ablysecured in the slot and corresponding in size thereto. and packingcompressing means cooperating with the closure.

3. A casing (lOStlIC consisting of a body having a vertical cablepassage of suflicient size to receive packing around the cable, a capmember projecting laterally from the body with a portion of the latterbeneath and a portion above the cap, the body and the cap at one side ofthe vertical passage .ot, a member re1nov-' formed with a cableentrnnc'cslot, a device reniovahly secured in the slot with portions of saiddevice corresponding in size to the slotted portions of the body and caprespectivel coiiperatmg with the closure.

4. A casing closure consisting of a body having a vertical cable passageof sufficient size to receive packing around the cable, a cap memberprojecting laterally from the body with. a portion of the latter beneathand a portion above-the cap,,tl1e body and the cap at one side of thevertical passage formed With a cable-entrance slot, :1 deriee' fittingthe slot with portions of said device corresponding in size to theslotted portions of the body and cap respectii'elg', laterallyprojecting lugs on the body and on i said device both above and belowtliil pap,
